Opis

In the second edition Steve Kesler (University of Michigan) has been added as an author to rewrite some chapters. The motivation for this revised edition is to more intensively address economic issues that surround the exploitation of mineral resources. This emphasis gives the book a unique character. With these sections Metals and Society deals with issues that pervade much of current science reporting - the rate of exploitation of natural resources, the question of when or if these resources will be exhausted, the pollution and social disturbance that accompanies mining, the compromises and challenges that arise from the explosion of demand from China, India and other rapidly developing countries, and the moral issues that surround mining of metals in lesser developed countries for consumption in the "first-world" countries. With its dual character, the book will be useful as an introductory text for students in the earth sciences and a reference volume for students, teachers and researchers of geography, economics and the social sciences.
